I had no doubts that you, OP, preferred Cornel to Berkeley, and that the issue was dollar value of the cost differential.
I think the answer to which school to pick, with that financial consideration in the picture is clear. Even die hard Cornell people here have agreed.
I’m also telling you that even without that differential in place, there are those who have carefully looked at both choices that would prefer Berkeley or other state schools to Cornell. There is an intensity, an edge, something about the atmosphere at Cornell that does not appeal to a number of people who have the direct choice of going there or to another school without the ivy luster, the NYC connections and higher rankings on standard lists. I see it all of the time because Cornell is s staple on college lists here in my area. No question at all, that it’s a great school and that those who complete there get a fine education and a boost in terms of finding sought after jobs. I wish some of mine had given Cornell the thumbs up (as well my alma mater, but there are those preferences)
You have two excellent choices. You are sitting pretty in that either choice is wonderful and you will be the envy of many regardless which one you choose.
